The UberPOP app was ruled illegal by the French government last year. But Uber has appealed the decision, insisting that its activities in France are legal.

Uber has a presence in six cities across France and serves over 500,000 customers. Of those riders, 160,000 people regularly use the uberPOP service.

Uber has faced a wave of regulatory and legal challenges around the world in the last year. It was temporarily blocked in Spain and had to tweak its services after a ban in Germany. It has also been suspended for a few weeks in New Delhi last year, after one of its drivers was accused of rape.
